if i remember correctly, it was a 75 hp shot. went from 11.7 @ 117 mph to 10.76 @ 128 mph.
Holly smokes!! Nice Improvement...
Was there a big learning curve as they call it? Or did you just heed all the warnings and kind of do it right the first time? And how was it set up? Did you have a separate fuel supply or split fuel supply that you had for the engine?..
